Research Data Sets: Climate

The climate of shortgrass steppe is semi-arid, with a mean annual precipitation (~340 mm) characterized by high inter- and intra-annual variability, with few large events and many events too small to infiltrate soils and feed plant transpiration. Mean annual temperature is ~8 C and the absence of climatological barriers to the north and south permit large variations in temperature. Like most grasslands, evapotranspiration far exceeds precipitation during much of the growing season. Understanding how the SGS responds to changes in climate requires expansive monitoring of abiotic and biotic variables (see Long-Term Monitoring datasets). Using comparative and experimental approaches, we study how changes in precipitation regimes, using the pulse-dynamic framework, affect soil moisture as well as above- and belowground community structure and interactions, nutrient dynamics, aboveground trophic and disease interactions, plant phenology, and plant genotypic structure.
